Vaginal cysts are closed pockets of air, fluid, or
pus located on or under the vaginal lining. There are several types of
vaginal cysts,
which can be caused by injury during childbirth, fluid
buildup in your glands, or benign (noncancerous) tumors within the
vagina.
Vaginal cysts are not likely to cause a woman any noticeable symptoms.
Depending on the size and location, she may or may not feel the lump
from the cyst. Often, a gynecologist will discover cysts during a routine, yearly examination. The cyst might stay the same size or grow larger over time.
Most cysts will not be painful. However, some of the larger cysts may
cause discomfort during sex, while walking or exercising, or inserting a
tampon. Cysts are most likely to cause pain if they become infected. Normal bacteria from the skin or sexually transmitted diseases may cause a vaginal cyst to develop an infection that may lead to an abscess.
The most likely complication from a cyst is an infection that causes an abscess. An abscess is a large collection of pus and fluid that can cause redness, pain, and swelling. If an abscess forms, it may need to be drained in order to heal.
A large number of bacteria both on the skin and from sexually transmitted diseases, such as chlamydia and gonorrhea, can cause a cyst to develop into an abscess. In other cases, bacteria normally found in the gut, such as E. coli, can lead to a Bartholin's abscess.
A woman should have an annual gynecological examination as part of
normal, routine care. In addition, it is a good idea for a doctor to
check any new lump on the vagina to ensure it is benign.
Women should also seek medical attention if a vaginal cyst or lump becomes painful or shows signs of infection.
